A Facebook friend, a few days ago, wrote that she was trying to decide what to give up. I wondered why she wanted to give anything up, why she didn't resolve to do something positive instead. It's easier to do something than to not do something.
Instead of giving up chocolate, why not resolve to eat a piece of fruit or some raw carrot before you have the chocolate? Chances are, by the time you've chomped through a carrot or banana, you won't want the chocolate, or if you do you'll be so full up you won't eat as much.
